BUG: "Missing Operand" Error Message When Using a Function

ID: Q117356

The information in this article applies to:

SYMPTOMS

When you are typing in a function and the return value from the function contains an expression, the error message "Missing Operand," is returned if the expression is not placed inside parentheses.

For example, if you create a function called TEST and type the following code in the function 

   FUNCTION TEST
   X=.T.
   RETURN X= .NOT. .F.
when you type "?TEST()" (without the quotation marks) in the Command window, you will receive the error "Missing Operand."

RESOLUTION

To avoid this problem, either enclose the return value for the expression in parentheses or reverse the order of the expression. For example: 

   RETURN .NOT. .F. = X

   -or-

   RETURN X = (.NOT. .F.)

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
